New furanocoumarins and other chemical constituents from Ficus carica Root heartwood

Abstract

Two new furanocoumarins, 5-(1",1"-dimethylallyl)-8-methyl psoralen (1) and 2"-O-acetyl oxypeucedanin hydrate-3"-methyl ether (2), were isolated from the root heartwood of Ficus carica Linn. together with three known furanocoumarins, two triterpenoids, two long-chain compounds, and a steroid. Their structures and relative configurations were elucidated by spectroscopic methods (IR, HR-ESI-MS, and NMR) and by comparison of their NMR spectral data with those of related compounds. © 2013 Verlag der Zeitschrift für Naturforschung, Tübingen.
